SAFETY FLUID-TRAP.

SPECE'ICAEON forming part of Letters Patent No. 303,822, dated August19, 1884.

Application iled October 8, lSE'l. (No model.)

To aZI/ whom, it 'nw/ 1j concern:

Ile it known that l, RUDOLPH DHEUREUSE, a citizen oi' the United States,residing at New York city, in the county and State ot' New York, haveinvented certain new and usel'nl Improvements in Safety Fluid-Traps, olwhich the following` is a specifi cation.

. This invention relates to traps used in dwellings, publie and privatebuildings of all kinds, to prevent the entraneeot' sewengas (so called)through. the waste-pipes of washbasins, sinks, bath-tubs, water-closets,die., into'the building.

It is the object of my invention to prevent any communication betweenthe sewer-pipes and the interior of the building from taking place byreason of the siphoning or drying ont of the water in the trap, and toapply disinfeetants or dcodorizers to the trap in a convenient,constant, economical, and effective manner.

My invention consists of an attachment to ille trap, comprising, amongother features, an air-iight vessel by which water disinfectants ordeodorizerin solution are carried in small quantities into the trap, andthe water in the saine is at once renewed whenever it gets low enough toopen or threaten air-commnnica tion with thesewer-pipe, acting uponthewellknown principle that a perfectly airtight vessel full ofwater,with an opening below which dips in water and is elosettby it,cannot discharge the water unless air is admit-ted by the orifice risingabove the water that closed it. The i'low from the vessel will then beexactly equivalent to the volume of air admitted,and will stop againimmediately when the opening ceases to admit air.

In the drawings annexed, Figures l and 2 represent partly sectionalelevations ofthe device, and Fig. 3 an elevation of part of Fie. 2,showing a different View.

The saine letters indicate corresponding parts in all the figures.

A is a trap, t here representing a siphon CD trap) in which Z) is theoverllow-water line, a, the waterlinc at or below whichair-communication would become established (below the top of the lowerbend ot' the trap.)

(3 4a hole in the trap, between the waterlevels b and ci or the open endof a pipe enter ing the trap higher up, communicating directly (see Fig.l) or by pipe d.' (see Fig. 2) with a close vessel, E, to be always keptfilled with water, disinfectant, or deodorizer in solotion above thehole or orifice C. I have shown the connection C at that side of thetrap at which the water enters. This is important, because it presentsthe hole so that the flow of the water through the main pipe. tends toassistthe operation. The cock f serves to Alill the vessel E when thewater gets low, and may be preferably constructed so that on opening itthe air in E is allowed to escapetor instance, by air-vent g in cock f,Fig. 2-though a separate ai r-vent may be applied, (g, Fig. l.)

To avoid possible omissions, it is preferable to lill with water anddischarge the air by the same movement, and the connection of the leverarrangement ot the cock-stems off and g by rod n. Fig. l represents amode by which it can be effected.

The crank p to eockstcnif g, Figs. 2 and 3, and p to cock-stem 7i, bothcranks connected by rod a, represent an arrangement by which f and g mayopen while simultaneously 7l. closes and opens when f and 9 close. Theair is discharged from E,`which fills with water without allowing, inthe meantime, the water to run into the trap through pipe d.

In Fig. 2, d l indicate several pipes leading from vessel E, which maysupply more than one trap at about the same level, the pipes cl d to berigid or flexible. A Heat, D, Fig. 2, in dotted lines, with itsconnections to the rod that operates the `filling, air discharging, anddistributing cocks or valves, is shown, to indicate that theseoperations may be performed automatically when the water in E falls low.It is plain that the vessel E can be 'Filled by other modes than by cockf, ior instance, a cap may be unscrewed and a funnel used, or some othercontrivan ec employed without connected movements.

In Fig. 2, r is a water-gage, to be employed when the vesselE is ofmet-al or other opaque material. It the vessel E beoi' glass or partlyglass,the lowering ofthe water-level in E would be readily observedwithout such gage.

To describe the operation olf the device, suppose the vessel Eis iilledwith water, dsim IOO fectant, or deodorizing solution, so much ol' itwill run out at C into the traps on closing the cock f and air-vent gand opening the cock h to pipe d, Figs. 2 and 3, as to expand whateverair may be left in E exactly conformably to the difference between thelevels of water in E and water-level b of the trap, when no more watercan iiow from E, this vessel being perfectly closed excepty toward thetrap. As soon, however, as the water in the trap, by evaporation orother cause, sinks below the upper edge of the orifice C, some air willimmediately enter and ascend. through the water into E,from which acorresponding amount of water, disinfectant, or deodorizer will flowinto the trap until the hole or orifice C is covered with water, when,by reason of no air being admitted, no more water can flow from Il.Aslong, therefore, as water remains in E or pipe d above the hole C ororifice C of pipe d,there is safety against entrance of sewer-gasthrough the trap.

rlhe operation of the device where pipe d serves for connection with Eis precisely the same as by immediate contact of E to the trap. In placeof communicating by the hole C, the pipe d may enter the trap at anyplace above the water-level b, (see d in dotted lines, Fig.

2,) extending downward and opening below the water-line b, and aboveline a by an orifice, C, the operation being the same as abovedescribed, and the device applicable to traps of whatever description. Asmall hole is all that is required for G-say one-half to onefourth inchdiameterto admit all the air or water intended to pass through it, whilethe pipe or connection with E may widen immediately. The hole or orificeC of pipe d at any place in the trap between the high level b and lowlevel a will accomplish the purpose, so that the water in the trap maynot fall and remain below a. Provision can be easilymade by any suitabledevicefor instance, by a pin to be worked from the outside, or connectedwith cocks or equivalents f or h-to move simultaneously to preventchoking up of the hole G by lodgement of impurities.

Frequent disinfecting or deodorizing of traps and connections is ofvital importance. The mode by which it is ordinarily donethat is to say,to pour into the basin or closet at intervals a solution of .thedisinfectant-is wasteful,inconvenient, and unreliable. This -is greatlyimproved by feeding the disinfectant or deodorizer in solution by a trapsupply-vessel, in the manner described, discharging automatically intothe trap by hole or oriiice C of pipe d, above the lower water-level, a,and below b, so as to keep the water-seal constantly intact, even forweeks or months of disuse of the trap.

Modifications may be made in the details. For example, in place of thecocksf, g, or 71, valves may be used, and other arrangements forconnecting their simultaneous operation applied, Y

Parts of the invention may be used without the whole.

The invention may be used with no mechauical connect-ion between thecocks f g h, care being taken that the operator shall understand andalways work the cocks simultaneously.

I claim as my inventionl. A trap for waste-pipes, washbasins, andanalogous uses, combined with a close or airtight vessel for water orliquid disinfectant or deodorizer, and provided with a dischargeoutletwhich communicates with the interior of the trap between the overflow ordischarge level and the sealing or safety level thereof, whereby thewater in the trap is prevented from falling below the danger-line,substantially as described.

2. In combination with a trap, the vessel E, constructed as described,and having a discharge-outlet which communicates with the interior ofthe trap between the overflow and danger levels, and provided with awater-supply pipe and devices whereby water may be admitted thereto andair discharged therefrom simultaneously, substantially as and for thepurposes set forth.

3. In combination with a trap and the close vessel E, having acommunication with the interior of the trap between the overflow anddanger levels, the water-supply and air-vent valves or cocks and cutoffl1., and devices whereby when the water-supply and air-vent valves areopened the cutoff l1 is closed, an d vice versa, substantiallyY as andfor the purposes set forth.

4. In combination with a trap, a close vessel having a communicationwith the interior of the trap between the overflow and danger levels,the said communication opening into the trap in the direction of theflow, substantially as and for the purposes set forth.

5. In combination wit-h a trap, the close vessel E, provided with thedisehargepipe d, which communicates with the interior of the trapbetween the overfiow and the danger levels', substantially as set forth.

6. In combination with a trap, the close vessel E, provided withwater-supply and airvent cocks or valves and a discharge-pipe, d,

which communicates with the interior of the VVhand this 5th day ofOctober, 1883.
